4 Claims.

This invention relates* to looks, and has special reference to looks of the multiple tumbler type; and an object of the invention is to provide an improved lock of the multiple turnbler type comprising a rotary actuator for moving a lock bolt and a series of tumblers movable approximately parallel with the axis of the actuatorV to positions to permit and to prevent rotation of said actuator, in combination with a key member for moving said tumblers.

Another object of the invention is to provide an improved look possessing all of the advantages of the look herein disolosed, reference being made to the aocompanying drawings, in which- Fig. l is a side elevation of my improved lock.

a In the embodiment of the invention shown, my improved lock oomprises a plate 1 whiohmay `be a metallic doorv or may be a separate element at- A housing is rigidly attached Vto'said plate 1 and oomprises a metallicl member shaped to provide an outer wall 2; side walls 3, an end wall 4, and an opposite end wall having therethrough an opening for projection and withdrawal of the locked bolt. The walls 3 and 4 are formed with a continuous laterally extended fiange' which seatsagainst the wall member l and is rigidly attached thereto byappropriate fastening means suchl as rivets 7.

The plate 1 supports a, series of llaterally extended'posts 8 of strong and' rigid construction, having therein circumferentiallgrooves 9 in which the lock bolt 10 is mounted for longitudinal sliding movements toand from lookinggposition.

Thus, the posts 8 and the grooves 9 therein oonstitute supports and guides for the lock bolt 10, so thatv said look bolt is properly guided and supported in its movements and cannot become disarranged.

' A barrel 11- is rotatively supported by the plate 1. Said'barrel 11V is mounted in a hole in the plate 1 andisformed with a circumferential flange 12 seating against the side of said plate that is covered by theuhousing wall 2. VSaid flange 12 is engaged inV a groove formed in a ring 13 that is rigidly seoured to the plate 1 by rivet fasteners 14 or other'appropriate fastening means. The ring 13 is formed with an annular flange lthat'enciroles the inner end of the barrel 11 and has, at: its inner end, an inwardly extended fiange 16 extendng across the peripheral portion of the .inner endrof said barrel 11 (Figs. 3 andli). Thus, the barrel. 11 is free to turn in itssupport comprising the plate 1, the ring 13, the fiange 1 5 and the flange 16. i'

The barrel 11 is operatively connected with the bolt 10 and is manipulative to move said boltv 10 to and from looking position. An appropriate form of connection for this purpose is shown, the same comprising a plate 17 rigidly attached to the inner end of the hub l18 'of the barrel 11l by a fastener 19, and having a crank pin 20 'project- `ing into aslot 21) in the look bolt 10. Thus, it is apparent that turning of the barrelll from a starting position will project the look bolt `10 `to looking position, and turning of the barrel `11 to its starting position will move the lock bolt 10 from looking position. v

VThe plate .1'7 has its edge extendedltoward the plate 1 to v.form a skirt 22. The edgeof the skirt 22 terminates near but out of contact with the end of the fiange 15.V It is now olear'that the actuator described oomprises a crank that is rotative about an axis of the barrel 11 from and to a starting position. The starting position may be considered thatposition in which the crank pin 20 holds the lock bolt 10 retracted within the lock housing,- in whichposition said look bolt is out of looking position. Turning Aof the actuator in one direction from this starting position moves the look bolt outwardly to locking position, which is clearly .shown in Fig. 2 ;of the drawings.` The grooved construction of the-rigid posts 8 oons'titutes vsupports and guides for supportingvand Vguidingthe lock bolt in these ;movements and forpositively preve'riting the lock ;bolt from becoming disarranged orV dislocated- The barrel 11 is provided With va circular series of holes,each`comprising an Vinner enlarged portion 23 and an outer portion 24 in axial alinement with and of Smaller diameter than the inner portion 23. This construction provides an annular Shoulder 25 at the communicating ends of the hole portions 23 and 24. In each of these holes a cylindrical tumbler is mounted. Each tumbler comprises an enlarged inner portion 26 separated from an enlarged intermediate portion 27 by a circumferential groove 28;V and an outer portion 29 of less diameter than the portions 26 and 27. Each of these tumblers 'is mounted in a hole 23, 24 and is normally held in position in which the outer ends of the enlargements 27 seat against the Shoulders 25. In such positions, the reduced outer portions 29 of these tumblers are in the hole portions 24, the outer' ends of the tumblers being approximately flush With the outer surface of the plate 1. The flange 16 is formed with a series'of notches 30 having curved walls in continuation of the walls of the hole portions 23. In the outer positions of the tumblers, the inner enlarged portions 26 of said tumblers are engaged in the notches 30. When the tumblers are thus engaged in the notches 30, it is impossible to rotate the barrel 11' because the member'in which the notches 30 are fornied is rigidly attached to the plate 1 by the fasteners 14 or otherwise. In order to permit'rotation of the barrel 11, it is necessary to move all of the tumblers inwardly until the groovesl 28 are opposite the flange 16.v The notches 30` are deep enough to disengage the tumblers from the flange 16 and permit rota- .I tion of the barrel 11.

The tumblers are tubular, being open at their inner ends and closed at their outer ends (Fig. 3). Pins 31 rigid with therplate 17 project into the inner ends of the respective tubular tumblers.

Coiled Springs 32 have their inner ends bearing against the plate 17 and encircling the pins` 31. These Springs Vextendoutwardly into the respective tumblers, having theirouter ends bearing against the outer end walls of said tumblers and thus actuating the tumblers outwardly to positions in which `the ends of the circumferential portions 27 of said tumblers abut'against the Shoulders 25. In Vsuch position of the tumblers, the parts 26Vof said tumblers are seated in the notches 30, thus positively looking the barrel 11'so that the lock mechanisrn cannot be manipulated. The construction and arrangement and relationship of these parts are such that, in either the vinner or outer position of the lock bolt 10, the tumblers can assume looking positions in which'the tumbler parts 26 are in the vnotches 30 and thus prevent operation of the lock. V

As vclearly shown in Fig. 10 of the drawings, thegrooves 28 are at different distances from the inner ends of the respective tumblers, thus leaving the tumbler portions 26 of the respective tumblers of different lengths. Because the tumblers themselves are of the same length, this construction requires that the tumblers be pressed inwardly different distances according to the distances ovf'the grooves 28 from the inner ends of the respective tumblers, in order to disengage the tumbler portions 26 from the notches 30 and to place the grooves 28 in registration with the notches 30 and, therefore, in registrationwith the fiange 16`to unlock the'barrel 11 so that said bar- 'rel 11 can be rotated; If any tumbler be moved too far its portion 27 will engage the notch 30 and lock the device. VIt is clear that'these'tumblers lmay be located in any arbitrary position and that the tumblers in one'lock may be located in different relationship than any other locks, so that the same key device cannot be used for opening different looks.

A key device for opening this lock is sufiiciently shown in the drawings, comprising a handle 33 having a post 34 projecting laterally from one end portion thereof and rigidly supportingv a plate 35. The plate 35 has a pair of peripheral` projections 36. A series of lugs 37 project from 'the plate 35 oppositely from the handle 33 and are arranged and located so that, when the post 34 is inserted in the hole 38 of the barrel 11, said lugs 37 I may be brought into registration with the tumbler ends 29. These lugs 37 are of different lengths according to the lengths of the tumbler portions 26, so that proper application of lthe key will press all of the tumblers inwardly Vthe same fasteners 14 that attach the member 13 to said plate 1.. The ring 39 has an inwardlyextended fiange 40 provided with spaced notches 41 through which the projections 36 may pass in order to permit application of the key to operate the lock.

In applying the lock, the post 34 is inserted in the hole 38 and the projections 36 are caused to pass through the notches '41, thus locating the lugs 37 in alinement with the tumbler ends 29. The key is moved inwardly until the plate 35 engages against the outer end of the barrel 11, thereby causing all the lugs 37 to move inwardly corresponding tumblers to positions in which the grooves 28 of all the tumblers are in registration with the flange 16, in which position the barrel 11 is unlocked and may be turned. In such position of the key, the lugs 37 being engaged in the hole portions 24, will rotate the barrel 11 and thereby the plate 17 and the crank pin 20, and thus move the lock bolt 10 outi' wardly to lookingV position, which is shown in Fig. 2 of the drawings. According to the coniio struction shown, it is impossible to detach the key from the lock-when the lock bolt is retracted or unlocked, because the projections 36 are engaged under' the fiange 40. However, when the key is operated to rotate the barrel 11 to position in which' the lock bolt is extended outwardly. to locking position, the projections 36 are opposite the notches 41 and the key may be 'detached It will be understood that the location and relative arrangement'of the long and Short lugs 37 will be varied according to the Variation in the location and arrangement of the tumblers. This Variation in the arrangement of the lugs 37 is necessary in order that the longV lugs 37 may be brought into engagement with the outer ends of the tumblers lhaving long tumbler portions l26, etc.

released positions of the tumblers, so that there is no possibility of any unauthorized person manipulating and releasing the lock.

The construction, arrangement and relationship of the parts may be varied otherwise than as specifically suggested without departure from` the nature and principle of the invention. I do not restrict myself in any unessential respects, but what I claim and desire to secure by Letters Patent is:-
